SPECIFICATION forming part of Letters Patent N0. 788,805, dated May 2,1905.

Application filed November l, 1904. Serial No. 230,983.

To rtf/ when it may concern:

Be it known thatl, CHARLES J. WALZ, a citizen oi' the United States,residingin New York city, borough of Manhattan, New York, have inventedcertain new and useful Improvements in Disinfecting Apparatus, ot' whichthe'lollowing is a speciiication.

My invention relates to improvements in the class oi' disinfectingapparatus in which the disinfecting 'fluid is gradually fed from areservoir to the open air for evaporation and delivery in smallquantities to the place to be disinfected; and the object of myinvention is to provide means for controlling at will the amount offluid to be distributed and to provide for the more equal distribuion ofthe iiui'd for evaporation.

My invention comprises a casing provided with a Huid-containingreservoir, a fluid-1e ceiving chamber, means to regulate at will theheight of the iluid to be delivered to said chamber from the reservoir,means for transferring fluid from the chamber, and means for receivingsuch fluid and causing its distribution. Y

The invention also comprises the novel details of improvement that willbe more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming parthereof, wherein- Figure 1 is a side elevation, partly broken, of adisinfecting apparatus embodying my invention. Fig. 2 is a plan viewthereof, part of the cover being removed. Fig. 3 is a vertical sectionsubstantially on the line 3 3 in Fig. 2. Fig. 4L is a detail of amodiiied form of the valve for controlling the liow ot' Huid from the Ymain reservoir to the receiving-chamber, and

1 are perforated, as at 1*. Above the partition 3 is a mainfluid-containing reservoir 5, which is shown contained between an upperpartition (i, an inner wall 7, the lower partition 3, and the outerwalls or sides of casingl. The wall 7 opens through the top partition 6and 'fo rms a chamber 8 in conjunction with part of the casing 1 and thelower partition 3. (See Fig. 2.) The wall 7 at its lower portion has avertically-disposed opening 7, which in Fig. 3 is shown in the form oi'a slot providing com munication between reservoir 5 and chamber 8, and 1provide a valve device (shown located in chamber 8)to control the flowoi'iluid from reservoir 5 to said chamber'. For this purpose I haveshown a tube 9 disposed vertically in chamber Sand provided with opposedopenings 9 9", shown in Fig. 3 in the form oi' vertically-disposed slotson opposite sides ol' tube 9, said tube being secured iiuid-tight to thewall 7, so that its opening 9 alines with opening 7 a in said wall topermit the passage of 'Huid from reservoir 5 to chamber 8. Vithin tube 9is a valve stem or rod 10, which is screw-threaded to mesh withcorresponding threads within tube 9, said tube being' threadedthroughout its length, the threads on rod 10 extending along' the samesuiiiciently far to enable said rod to be screwed down to positivelyclose the passage through openings 9 9b throughout their whole length.Rod Il() may have a squared .end or the like 10 to receive a keyinserted through the open end of chamber 8 to permit operating said rod.When rod 10 is screwed outwardly the desired distance, iluid fromreservoir 5 will ilow through opening 7lL 9" 9" into chamber 8 to theheight at which the lower end of rod 10re mains. Instead oi' havingslots 9u 9" in tube 9 said tube may be provided with a series ofvertically-disposed perforations, (indicated at 9.)

The partition 6 is shown provided with an opening 6", having a threadedneck 6, reeeiv ing a threaded plug 11, that is'provided with a bore 11opening through the bottom and one side of said plug, whereby when saidplug is screwed down tight, as in Fig. 3, the passage of air throughopening 6:x will be prevented, but when the plug is screwed outl rlhedetails of construction shown and dewardly sufficiently far air mayenter reservoir 5 through bore 11. By unscrewing plug 11 so that air mayenter the reservoir said reservoir may be filled by screwing rod 10outwardly and pouring the fluid into chamber 8, which will pass thenceinto the reservoir. If preferred, however, the reservoir may be filledthrough the opening 6, in which case the plug 11 may be removed, or, ifpreferred, a screwcap 12 may be provided on neck 6b, as in Fig. 5.

l/Vithin chamber 8 is a tube 13, that is shown extending nearly to the.top of said chamber and at its lower end opens through the partition 3,and at 14 is a wick that passes through tube 13, preferably extendingtherefrom into chamber 4, part of said wick also being located inchamber 8 and extending down substantially to the bottom thereof, as inFig. 3. By means of said wick the fluid from chamber 8 is by capillaryaction carried through tube 13 and delivered into chamber 4. /Vithinchamber 4 is a fluid receiver and evaporator 15, which is shown in theform of a shell, having relatively large perforations 15, a space 4being provided between shell 15 and the walls of casing 1. The top 15bof shell 15 is shown located below the Lipper edge 15c thereof,providing a shallow pan or receiver 15d for liquid delivered thereto bywick 13, the lower end of which wick is above such pan. At 16 is adrip-tube extending from the bottom 2 of casing 1 and communicating withspace 41.

In the operation of this device the reservoir 5 is filled with liquid,the valve rod or stem 10 is raised to the desired height, so that liquidwill enter chamber 8 to a height corresponding to the bottom 0f stem 10,and the wick 14 delivers such iluid to the pan or receiver 15d, whichfluid spreads out thereon and when said pan or receiver is filled theliquid overflows and slowly travels down the outer wall of shell 15,where the free circulation of air through the openings 15a assists incausing relatively rapid evaporation of such Huid, and the excess liquidflows upon the bottom wall of chamber 4a and passes through drip 16 tothe place to Vbe disinfected. The rapidity of delivery of fluid causedby wick 14 may be controlled at will by raising or lowering the valverod or stem 10, whereby to increase or decrease the size of the openingor communication between reservoir 5 and chamber' 8, to thereby regulatethe height of fluid in said chamber, for when no air is admitted to thetop of reservoir 5 the fluid in chamber 8 will only rise substantiallyto the height of the lower end of rod 10, even though the liquid inreservoir 5 is above the lower end of said rod, and the deeper wick 14dips into fluid in chamber 8 the faster will be the feed of liquid bysaid wick and the less the wick dips into said fluid the slower will bethe feed of iiuid by the wick.

scribed may be varied without departing from the spirit of my invention.

A disinfectingapparatus comprising a fluid-reservoir and a chamber for communicationwith each other, means to control at will the height of fluid in saidchamber flowing from said reservoir, means to cause evaporation of fluidfrom said chamber, and a fluidreceiver beneath said reservoir andchamber provided with a top and perforated side walls beneath said top,substantially as described.
